Locate the position of a 20-ship fleet in the grid. The shapes of the ships are shown to the right of the grid. There is two 4x1 battleship, four 3x1 cruisers, six 2x1 destroyers and 8 1x1 submarines. But in the grid is only a subset of this fleet. The numbers beside the grid indicate the number of cells occupied by ships in each row, while the numbers below the grid indicate the number of occupied cells in each column. Ships may touch the edge of the board, but cannot touch each other, not even diagonally. One cell is known to be water. Some cells are known to be ship parts.

Fill in the grid so that every row, every column and 3x3 box contains the digits 1 through 7 and two ship parts. So there are 18 ship parts for total. The ships are destroyer (2 unit ships) and submarines (1 unit ships). Ships cannot be adjazent to each other, not even diagonally. The numbers around the grid tell you how many ships you can see in this line.

Locate the position of the fleet in the grid. The shapes of the ships are shown to the right of the grid. The numbers in the grid indicate the number of cells occupied by ships in adjazent cells, including diagonally. Ships may touch the edge of the board, but can't touch each other, even not diagonally. Ships do not overlap the numbered squares.

Locate the position of a 10-ship fleet in the grid. The shapes of the ships are shown to the right of the grid. There is one 4x1 battleship, two 3x1 cruisers, three 2x1 destroyers and 4 1x1 submarines. The numbers beside the grid indicate the number of cells occupied by ships in each row, while the numbers below the grid indicate the number of occupied cells in each column. Ships may touch the edge of the board, but cannot touch each other, not even diagonally. Additional each cell has a number from 1 to 9. Place the digits so that each digit appears exactly once in each of the rows, columns and the nine outlined 3x3 regions. Cells with ship parts can only contain even numbers.

Locate the given fleet in the grid. The numbers beside the grid indicate the number of cells occupied by ships in each row, while the numbers below the grid indicate the number of occupied cells in each column. Ships may touch the edge of the board, but cannot touch each other, not even diagonally.

Locate the position of a submarine fleet in the grid. Each submarine needs one square in the grid. The number of submarines is not known The numbers beside the grid indicate the number of cells occupied by submarines in each row, while the numbers below the grid indicate the number of occupied cells in each column. Submarines may touch the edge of the board, but cannot touch each other, not even diagonally. Blue cells are known to be water.

Locate the position of a submarine fleet in the grid. Each submarine needs one square in the grid. The number of submarines is not known The numbers beside the grid indicate the number of cells occupied by submarines in each row, while the numbers below the grid indicate the number of occupied cells in each column. Submarines may touch the edge of the board, but cannot touch each other, not even diagonally. Blue cells are known to be water.

Ships may touch the edge of the board, but cannot touch each other, not even diagonally. One cell is known to be water. Some cells are known to be ship parts.
There is only one solution. You can find it by logic.
